The best load demarcation point between setting pressure and sliding pressure and the optimal initial steam pressure under different conditions can be obtained, which proposed a new method to optimize operation of the thermal power unit.

By the method the optimum initial mode is rapidly selected according to cavity temperature and known thermal model.

Comparison of Ensemble Kalman Filter with Optimal Interpolation in Different Observational Networks;

Observations of PM10,NO 2 and SO 2 by Shanghai Environmental Monitoring Center with necessary quality control were assimilated into the nested air quality prediction model,using the optimal interpolation approach.

The author firstly investigated commonly used data assimilation methods, pointed thatthe essence of all of them is a filtering process, and chose optimal interpolation (OI)and EnKF methods to build the two systems.

The result showed that there was an optimum running load causing the system running in lower energy consumption,and the two~dimension space composed of thermal capacity and ratio of dissipated heat energy to maximum dissipated heat energy,can be divided into several running regions,in which the optimum value was kept invari.

In this paper,a new method for estimating the global optimum value in a global optimization problem is proposed .

Confirm the optimum value of the area of campus and student s scale with people s behavioral yardstick,lie in,can derive,produce optimum value result naturally compared with traditional advantage of research approa.
